The lift check valve is a type of check valve that relies on the positive pressure of the medium to push the valve core (valve disc) up and down along the axial direction to achieve "flow", and the reverse pressure to make the valve core fall back for sealing to achieve "anti-backflow". Its core advantages lie in high sealing accuracy and stable structure, especially suitable for high-pressure, high-temperature and strict leakage requirements working conditions. It is widely applied in industrial fields such as petrochemicals, power, and pharmaceuticals.
The core advantages of lift check valves:
Compared with double-plate check valves and swing check valves, the advantages of lift check valves are mainly concentrated in three dimensions: "sealing performance", "high pressure and high temperature adaptability", and "resistance to impurity interference", as follows:
1. It features extremely high sealing accuracy and very low leakage
2. It has strong adaptability to high-pressure and high-temperature working conditions
3. Resistant to impurity interference and stable operation
4. The flow path is regular and the pressure loss is controllable
